IRIS Vulcan smoke possibility. ..

Hey people,

 

Long time lurker, first time poster.

 

I am a massive Vulcan fan, my Dad worked on them, I live 20mins from where XH558 is based and I love flying it in FSX. I have Just Flights model, and while its not super perfect, I added a sound file with the infamous howl (that is also missing off the IRIS model) and got used to the flying characteristics which was a challenge. But I digress.

 

The thing is on the IRIS model, as with the others, the smoke effect comes on when above a certain % of throttle to full power, however in real life the Vulcan smokes when it comes off full throttle after take off or part of display. So my question is, is it possible in the .cfg of the smoke fx file it can be changed so the smoke is on between a set percentage? I see parameters but at a lost what they are values for.

You can add smoke, which you would activate with the 'I' key, after the 'throttle controlled' smoke stops. You can find a smoke effect that puts out a smaller amount of smoke that would stay on no matter what amount of throttle you use, by adding a (Smoke) section to your AIRCRAFT cfg.

Thanks for your reply.

 

The thing is, I would want to it smoke only from say 30% to 80%, and wondered if it can be done by modding a config file somewhere, as I presume there is code to set the smoke to activate at a certain point, so can I change it?

Im sure I replied to this yesterday evening. Sorry if I repeat myself.

 

The point im trying to get across is this; is there a way to change when the engine smoke comes on in a .cfg file or similar. It would be more realistic if the smoke was on from say 30% throttle to 75% throttle, not like it does already.

 

The Vulcan doesn't have smoke from the engines in real life when they are fully open, and I was wondering if there was a way to do a mod to replicate this. I dont want smoke on all the time, just between specific points.

Check in your aircraft.cfg file for [smoke]. If you have something under that heading, then it's usually turned on/off with the I key. Some modelers will program in startup smoke for engine start and for the IRIS Vulcan they may have added some more which you probably can't modify.

If I may contribute purely from an interest viewpoint as Im not sure how to emulate the precise effect on the IRIS Vulcan, but I too worked on Vulcans in my time in the RAF and in particular on the engines. There was a smokeless modification implemented on some of the Olympus 201's and 301's on the combustion chambers. Inefficient fuel burn equals smoke at certain rpm ranges. In reality some Aircraft would have a combination of smokeless engines and pre mod smokeys. This allowed us to send up the gullible by claiming that it was standard operational procedure to fly on one engine (The smokey one if only one was fitted). This wind up won us a few beers occasionally :)

A late reply but.... but its somewhere in the file:

 

C:\Program Files\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\IRIS Vulcan B.2 RR201\panel\FSX_Vulcan_Gauges\SYSTEM_Effect_Controller.xml

 

and it looks like it's operated by No1 engine corrected N1 above 55%

 

I'm looking to modify the XML's due to building a Vulcan simpit... the first fix is to have four smoke effects, one for each engine that turn off when the engine dies.

Okay, I've done my research and have modified a gauge for the first time ever in 35 years of simming lol. Swap the code for this to get smoke between 55% and 75%.... with an added plus that you can turn off an engine and the smoke vanishes (which isn't default on the IRIS Vulcan)

 

(A:TURB ENG1 CORRECTED N1,percent) 55 > (A:TURB ENG1 CORRECTED N1,percent) 75  &&
       if{ (A:SMOKE ENABLE,bool) ! if{ 1 (>K:SMOKE_ON) } }
       els{ (A:SMOKE ENABLE,bool) if{ 1 (>K:SMOKE_OFF) } }






(A:TURB ENG2 CORRECTED N1,percent) 55 > (A:TURB ENG2 CORRECTED N1,percent) 75  &&
       if{ (A:SMOKE ENABLE,bool) ! if{ 2 (>K:SMOKE_ON) } }
       els{ (A:SMOKE ENABLE,bool) if{ 2 (>K:SMOKE_OFF) } }






(A:TURB ENG3 CORRECTED N1,percent) 55 > (A:TURB ENG3 CORRECTED N1,percent) 75  &&
       if{ (A:SMOKE ENABLE,bool) ! if{ 3 (>K:SMOKE_ON) } }
       els{ (A:SMOKE ENABLE,bool) if{ 3 (>K:SMOKE_OFF) } }






(A:TURB ENG4 CORRECTED N1,percent) 55 > (A:TURB ENG4 CORRECTED N1,percent) 75  &&
       if{ (A:SMOKE ENABLE,bool) ! if{ 4 (>K:SMOKE_ON) } }
       els{ (A:SMOKE ENABLE,bool) if{ 4 (>K:SMOKE_OFF) } }

So using the new gauge when you switch off an engine the smoke only disappears on that one engine. Well done. Congrats on your first gauge!

The possibilities are endless here... imagiine have more smoke at higher power settings. the &Gt and &lt mean greater than or less than... so in theory you could have a bunch of thick smoke effects firing at one engine setting and less dense smoke at lower settings.....

 

 

Yes, the key to this is the number in this part of the code

 

if{ 1 (>K:SMOKE_OFF) }

 

Its undocumented that the smoke fx has this attribute, but Tom (knivpekka) discovered it here

 

It switches on/off the smoke.o, smoke.1, smoke.2,smoke.3 lines in the aircraft.cfg file.... but the values are out of sync by 1 so use 1-4 instead. This technique can be used on all aircraft..

Thanks! I made a gauge once, but it sure doesn't come naturally to me. I'll print it and hope to ask some smart questions later.
